ITP Star Styli Type V with Ruby Ball is a precision measuring probe designed for large-diameter gauging and deep-hole applications. Ideal for metrology technicians and quality-control engineers, it delivers stiffness and versatility for challenging features like undercuts and threaded interiors.

• Configuration: Type V star styli with five fixed arms for stiffness and precise contact.
• Tip: Ruby ball tips provide repeatable, wear-resistant contact during measurements.
• Thread: M2 threads fit standard stylus holders and common measuring setups.
• Measuring length: 13.5 mm length designed for deeper gauging without compromising rigidity.
• Versatility: Fixed-arm design enables task-specific measuring programs for large-diameter features, undercuts, and threaded interiors.
• Part Number: SIM202005022

This star styli configuration minimizes deflection when probing long lengths, delivering stable, repeatable measurements of inner surfaces, threads, and bottom-of-hole features. The combination of ruby-ball tips and a robust five-arm geometry supports efficient setup and reliable results across a range of precision QC tasks, helping you achieve tighter tolerances with confidence.
